IMPROPER SUPPORT BRACKET INSTALLATION CAN SHORTEN THE CATALYTIC CONVERTER’S SERVICE LIFE

Walker® Ultra® direct-fit catalytic converter part number 16581 fits specific GM vehicles that utilize a unique converter support bracket secured with a single bolt, and a locating tab designed to fit into a slot in the engine block.

QUIET-FLOW® DUAL-SHELL DESIGN

Traditional mufflers use a dual-shell design made of two sheets of thin, aluminized low-carbon steel – one layer to seal the interior and another to cover weld points for a cleaner look. The primary disadvantage of this design is that it is prone to corrosion, due to the potential for moisture becoming trapped between the two layers and the inherently weaker rust resistance of low-carbon steel when compared with stainless steel. Walker’s Quiet-Flow® SS mufflers address these challenges by utilizing a direct-fit, single shell, stainless steel muffler design.
